Application filed August 25 1919. Serial No. 319,722.

T all whom it'ma-y concern-f Be it known that I, PETER G. GIELEN, a

citizen of" the Republic of France, residing at Paterson, 1n the countyof Passaic and State of New Jersey, have invented certain new and usefulImprovements in Looms, of which the following is a specification.

ThlS 1nvent1on relates to looms, and particularly to the type of loomsthat are -'de-' turning it at will and with a ratchet wheel @I which isengaged by a holding pawl and also by an actuating pawl 76, the lattermov: able up and down and held against the ratchet wheel by a spring Theup and down movement of the pawl I; is effected by l a lever m from alever 12', both fulcrumed in signed for weaving in 'an upright plane,

which is very desirable in the-weaving of 'certaln fabrics, asgeorgettas, in order to prea vent any possibility or the shuttleabrading the warps, and also because it enables the woven goods to bepositioned so that it is 1n plain sight of the weaver and easily acccording to this invention the,

cessible. batten is arranged to reciprocate vertically, being suitablyguided forthat purpose, and in order to prevent the intermittent shockincident to the change from the down stroke i to the up stroke of thebatten and so insure a smoother action of the loom I provide resilientmeans to assume the down thrust of the batten. invention consists inproviding'the batten structure with a shuttle box structure comprising aplurality.ofboxesshiftabh for. changing shuttles not .in a planetransverse to that of the mo'vementof the batten for beating up, as inthe ordinary loom, but up and down, substantially in the same directionas the batten moves for beating up, suitable connections between saidshuttle-box structure and the means in the frame for shifting it beingprovid'edso that its move- I Fig; 3 a fragmentary side elevation ofachain connection 6" ments take place regardless of the movements of thebatten structure.

The batten 8 is arranged? to move up and down and has fixedthereon 'reaartl carriers-8 which slide "up anti-d n fixed vertical shafts 9 vmol'lnted, a loom frame. The batten structure v with the cranks 10 onfthe: crank ushit by the pit'men ll. Due to the: Weight flf flt al battenstructure and to the ehangeyin the direction of its movement. fromdo'wntong j if crank shaft. here there are a large number of looms on a floorthis becomes a serious objection whenever the beats of the looms happento occur in the same cadence,

and of course 11. 1s in urious to the loom it self and more or lessspoils the quality of the fabric being woven. To eliminate this shock Imterpose springs '12, preferably coiled about the shafts 9, between theframe,

andthe under side of the batten, in the preferred form leaving aspacebetween the batten, when up, and said springs, so that the latter.will be effective as a cushion at the downward end portion of thethrow. This.

very considerably eases the action of the batten and practicallyentirely eliminates the shock and vibration referred to.

The batten has a vertical opening 13 (see Fig. 1, andalso indicated indotted lines in Fig. 2) through which the sheet A '15 extends, and onthe batten over this opening is fixed, horizontally, the reed 11-. Theshut-' tle 15 travels from end to end of the batten structure over thedents of this reed as a race, its movements being caused by any suitablemeans, picker sticks 16 adapted to be actuated'by tappets 17 on thetappet shaft 18 driven by a gear 19 from the gear a being illustrated byway of example. Any suitable harness motion the sheds maybe provided. Inthe illustrated construction I have shown a set of harness frames 20arranged to slide inhorizonta-l ways 21 in the frame a and all assumedto be normally held forward by springs (not shown). the same havingrear- Wardly projecting flexible connections 22 which pass around andare secured to conical sheaves 23 ployed, obviously',so as to obtain thedesired convergence in the warp shed) whose shafts 2 1 are journaledvertically have cranks 25 which are connected by a suit-able connection26 (see Fig. 2) with suitable operating means 27 actuated from aneccentric 28 on the tappet shaft 18. The arrangement of the sheaves andthe connections 22 is a well known one: that is, the frames 20 aregrouped in two sets, and one end of each connection 22 is attached to aframe in one set and the other to a frame in the other set, so that whenthe sheds are oscillated the sets of frames will be.recipro cated inopposite directions.

Thepresent loom is designed for the operation of two shuttles. At oneend of the batten 8 (Fig. 2) is a single box 29. At the other end is abox structure 30 including, in

the present case, two shuttle boxes arranged one above the other, thesame sliding vertically in a framing 31 forming an extension af thebatten structure.

for forming (conical sheaves being em Box structure 3,0'

has a fixed depending rod 32. Framing 31 has :1 depending bracket- 33 inwhich are journald iutermeshing bevel gears 31-35, the former of whichis connected with-rod 32 by the pitman 36 and the latter of which isconfined to move up and down with the bracket by being housed in a bend533 thereof. Bevel gear 35 is splined on and movable vertically of a.rotary shaft 3? which is journaled in bracket E53 and a fixed bracket 38on frame a, said shaft having no vertical movement and being connectedwith a horizontal shaft 39 by bevel gearing -10, and shaft 39 beingconnected with the tappet shaft by bevel gearing 41 (see Fig. 3). Theconstruction is such that due to the extensibleconnection (pe'rmittedbythe spline between 35 and 37) between the tappet shaft and the boxstructure 30 the box wardly, so that'lever 13 moves a sprlngpresseddagger 45 out of position, when the through a. spring elevated rod 47oscillate a lever 48 for imparting a thrust to a suitably guided rod 49which impinges the control lever a to'shift the same and stop the loom;obviously, if theshuttle fails to box properly lever t3 will not actuatethe dagger and so the loom will be stopped.

The general operation is quite similar to that of ordinary looms.Gearing a-19 being -1 to 2 and the tappets 17 diametrically in the frameand oppositely arranged on shaft. 18, the pickers (first one and thenthe other) are actuated on every reciprocation of the batten structure,while thetwo sets of harness assume their limits of movement, oneforward and the other'back, on every such reciprocation,

thus to form'the sheds, because eccentric 28 is arranged on shaft 18,which performs a half revolution to every full revolution of shaft y.Every time a shuttle is thrown across the loom from its box in structure30 and back again said structure is shifted up or down from shaft 18, itbeing noted that the gear ofigearing 411 which is on the shaft 18 hasall but a few of its teeth absent.
